A chute or troughlo is suitably mounted on table top 1 and is shown provided with open ends and an open top, the chute or trough having its inner end located substantially in horizontal alignment with the adjacent end of acontainer A on the conveyor, (Figs. 1,8 and The labels B are stacked on edge inthe chute and are normally pressed toward the inner or delivery end of the chute by means of a finger or pusher 16, the inner or endn'iost label being normally stopped against spaced projections or p *ongs 1?,tsl1own secured to the chute, (Figs. 3 and, 10). The projections or prongs 17 hareinclined faces 10* cated at an acute angle inwardly disposed respecting the longitudinal axis of chute 15 so as to obstruct the stack of labels and yetpermit the endinost label to be with drawn as required, the edges of the labels slipping along the inclined faces of the projections when withdrawn from the stack by means'of a transferring head. 18 through which air is induced at the proper time to cause the endmost label to adhere to such head, and which exhaust of air through the head is stopped when required torelease the label. The finger 16 projects into the top opening of the chute15 from a plunger 19 slidable in a guiding tube or casing 20 supported on the main frame, (Figs. 2, 3 and 9), the tube 20 being shown provided with a longitudinal slot 20 through which the inner end of finger 16 as well as a handle on finger piece 21 project from the plunger 19. Within the tube or casing 20 is a coil spring 22 hearing at one end against plunger 19 and at'the other end against a head 23 atone end of the tube, whereby the plunger is normally pressed in such a direction that the finger 16 will normally bear against'the stack of labels B. The tube or casing 20 is shown provided with pivots 24 at opposite ends which are journaled in bearings at 25, 26, whereby said tube may be rocked. When a stack of labels B is placed in the chute 15 the finger 16 is first drawn from the chute as by rotating the tube 20 and pushing the plunger outwardly against the tension of spring 22, and after the labels have been placed in the chute the finger is restored behind the labels so that the spring maintains a normal pressure against the stack of labels forcing them against the projections 17 with the desired pressure. An advantage of the construction described is that the operator may place the labels in the chute without stopping the progress of the machine since the labels in the chute may be kept pressed manually toward the projections 17 while another staclrof labels is being placed in the chute behind the other ones. The exhaust labeltransferring head 18 is to be moved back and forth between the end of the stack within hood 32.

of labels in the chute '15 "and the end or side of a container A on the conveyor to receive and apply labels, and during'such time the head 18 isrotated from label r ceiving to label applying position and reversely by means arranged as follows.

The head comprises member 18, (F gs.

8' and 10), having a longitudinal bore 18 and a port 18 opening through the label receiving face of the head, a tube entering the bore 18 and resting at its inner end against the shoulder 18 therein to make a tight lit, the upper end of'whiclr tube is provided with a gear 28 upon which rests 1 the laterally disposed flange or e1:-

tension 2 9 of a hollow cap 29, the head 80 I or a threaded rod 30 bearing agains' the outer end of said cap and extendingthrough the bores of said cap, tube27 and bore 18, the lower threaded end of said rod being screwed into a threaded hole in head 18, whereby the parts are secured airtight together to rotate. The cap 29 provided with one or more openings 31 for air. Outside of cap 29 is a hollow'hood 32 whose lower enlarged end rests upon the flange 29 of cap 29 and said hood is provided with a nipple 33 to which an air hose 8%- is attached, said nipple communicating through an opening 35 in the hood with the opening 31 in cap 29, Wherebyvthe air is induced through port 18 into head 18 and thence through opening 31 to hose W hen the head rests against the endrnost label in the corresponding chute lo the label will be retained against the head by reason of the exhaust therein. ,A pin 36 carried by a support 37 enters an opening in hood 32 to retain the latter in proper position. Vlhen the aforesaid exhaust occurs the flange 29 will be drawn tightly against the top of gear 28 to maintain a tight lit and prevent the loss of air,while at the same time the cap 29 may rotate with gear, 2" The gear28 is supported by a bearing 38 carried by a slide member '39, which bearing also serves as a'bearing for tube 27, and since gear 28 rests upon bearing 88 the exhaust head 18 is pivotally supported. The slide 39 is mounted to reciprocate in guideways 10 mounted upon the main frame transversely over the conveyor and said slide is provided with a rack 41 in engagement with an arcuate gear on an arm l3 secured'on vertical shaft l 'journaled in suitable hearings on the main Ill) - shaft'48 is shown provided with a.

beveled gear 19 iii mesh with a corresponding gear secured on shaft 51 Jouriialed in bearings on the main frame, (Fi s.

and 3), which shaft is shown provided with a gear 52 iniiiesh with a gear 58 iecurel ona shaft. 5- jo irnaled on the main frame Shaft 54:,i-s rocked by means of an arm secured thereon and having a projection or roller 56 cooperative with a cam 57 'se-- cured on shaft 58-journaled on the'niain frame, (Figs. 1 and 8). Shaft 58 is shown provided with a gear- 59 in mesh with a ge 1: 60; on shaft 61 journale'd on the main frame. and shown provided with a drive pulley 62 which may be operated by a belt from a suitable source of power or in any other desiredway, (Fig. 8)) lVhe'n shaft 5 1 is rocked the shafts 44 will be correspondingly rocked through the gears and arms before described for reciprocating the slide members 39. A segmental gear 63 is pivotally supported on the corresponding slide member 39 at 6 1 and in mesh with the corresponding gear or pinion 28, (Fig. 2). The segmental gear 63, on the side of pivot 64opposite its teeth, carries a projectionor roller 65 operative in a cam-like groove-66 provided between members 67, 67 -When the parts are in the positions shown in Figs. 2 and 10 the exhaust head 18 will be in position with its port'18 pressed against the labels B, (Fig. 10), and the segmental gear 63 will be in the posi tions shown in Fig. 2,and when the slide members 39 are moved inwardly respecting the conveyor the projections 65, by operating in the straight portions of slots. 68, will move the heads 18 and the labels there on from chutes 15, and the heads will come to rest for application of adhesive tosaid labels at the dotted line position a; in Fig. 10, and then as the projections 65 operate in the curved portions of the corresponding cam slots 66, they will cause the segmental gears (38 to rock to actuate the gears or pinions 28 for rotating the corresponding head 18 from the adhesive applying position. at a; in Fig. 10, to the label delivery position shown in dotted lines 3 at the left hand side of Fig. 10, during the travel of slide 89 which transfers the head 18 from the label receiving to the label delivery position. lVhen the slide 39 returns on the corresponding stroke the head 18 will be returned to label receiving position at the end of chute 15, duringwhich time the segmental gears 68 will rotate the head 18 reversely from the label delivering to the label receiving posit-ion. By the means described for each to and fro reciprocation of a slide member 39 a label will be attached to a head 18, paste will be applied on the label and the latter will be delivered against a side or end of a container A, and

the head will be. returned. to label freceiving position, such movements of the head 18 occurring during the stepby-step applied to the labels, 1' provide grippers 6'8,

(Figs. 1 3-and 10) ,which are pivotally sup. ported at 69 upon brackets 7 0 carried by head 18, which grippers are shownprovided with projectingtongues 71 adapted; to engage the ad acent edge of a label and retain itaganist the side of head 18; The gripper 68 is pivotallyconnected at 7 2 with a link 7S thatfis pivotally connected at 7 1 with a sleeve 75 that is mounted to slide on an end of the extended part 18 of member 18 and on tube 27, (Figs. 8 and 10) A coil spring 76 within sleeve 7 5 bears'at one end against the sleeve and at theother end against the part 18 normally tending to press the sleeve upwardly and thereby through link 7 3 "to actuate gripper 68 so that its tongue 71 will engage a label'again'st the face of head 18. Atthe label receiving position the outer end of sleeve 75 is adapted to engage a cam-like stop 77, and at the label delivering position the said end of sleeve 75 is adapted to engage a cam-like stop 78, which stops are in position to depress sleeve 75 and thereby through link 7 8 to cause gripper 68 to be depressed out, ofthe path of the labels and chute 15'. l Vhen head 18 moves away from V chute. 15 the sleeve 75 will pass from stop 78 and thereby said sleeve will rise and cause gripper 68 to engage and retain a label at the face of. head 18, and when said head has been moved toward the conveyor a proper distance tliesleeve 75 will engage stop 78 and will be depressed to cause gripper 68 to release the label adjacent to the container A. During the progress of the" label with head 18 from label receiving to label [delivering positions the gripper 68 will serve to keep the label from being displaced from the head notwithstanding the exhaustoperating against the label within the head.

During the time the head 18 with label thereon is being transferred from the label lli) iio"

receiving'to the label applying position ads hesive is applied to the face of the label that is'to be applied against a container For such purpose I provide the following arrangeineiit:-a reciprocative head 7 9, v (Fig. 3), is guide-d along an upright 80 on the mainframe and is shown provided with a depending link 81 pivot ally connected at 82 in pairs. Between the upper ends of each pair of rods 88 rollers 89 are 1ournaled and are reciprocative laterallvin position be tween the. corresponding chute and label by rods 88,

. indicated 1.

transferring head'18 to apply adhesive, such as paste or glue, to the exposed surface of the label on head. 18. The shafts of rollers 89 are carried by blocks or heads 88 supported said heads havingrecesses 88" l .er'l guides or webs 90? that project from up; ,,,ht guides 90 carried by the main frame. The guides 90 are provided at the lower ends with downwardly and outwardly inclined slots 91 to receive the shafts of the rollers 89 and guide them laterally so the surfaces of the re rs will be pre sented to adhesive distributing rollers 92 journaled on and operative in tanks 98 for the adhesive, (Fig. The shafts of the rol ers 93 are provided with gears 9-1 in mesh with gears 95, 95 respectively. The shaft 01 gear 95 is shown provided with a sprocket wheel 96, and gear 95 is shown in mesh with a gear 97 whose is: provided with a sprocket wheel 96. An endless chain passing over the sprockets 96, 96 and over sprocket 99 on shaft 61 serves to rotate the that receive adhesive distributing rolls 92 continuously.

lVhenthe rollers 89 are depressed and their shafts enter the slots 91 the rollers will be gu ded into contact with the distributing rolls 92 to receive adhesive therefrom, and when the rollers 89 are raised they will pass into engagement with the label that is on the corresponding head 18 that will have been brought to restat a distance from the adjacent-chute the position of head 18 dotted lines at m in Fig. 10, to apply adhesive to the label. In such position of the parts the grippers 68 retain the labels against heads 18 to prevent the labels from being rolled away from the heads when ,the rollers apply adhesive to the labels. The head 18 will continue toward container A. to apply the label thereto and roller 89 will be depressed, and so on successively. The head 70 is shown provided with an upwardly 6X- tending rack 100 in mesh with a gear 101 whose shaft 102 is journaled on a bearing 103 on table top 1, the gear 101 being in mesh with a rack 10% on rod 10, whereby as the head 9 is reciprocated the rod 10 will be reciprocated step-by-step for correspondingly operating the conveyor.

Means for producing exhaust in and releasing the exhaust from the label. transferring head 18, and also for blowing heated air against the label when it has been applied to a container, are arranged as follows :-thc hose communicates with a tube or inanifold 105 shown supported by an arm 106, (Fig. 2), and in communication with a pipe 107 that communicates with an air inlet or suction port 108 in a valve casing 109 supported'in the main frame, (Figs. 1, 11 and 12). valve 110 adapted to be rocked and provided with an arm 111 actuated by cam 112 on shaft 58. A sprin 111 connected with arm 111 and with a stop 111 causes the said arm to cooperate with cam 112. 109 is provided with anair outlet port 118 connected by tube 114 with any suitable exhaust apparatus (indicated at e in Fig. 1),

for inducing suction through pipe 107 and thence throughhose 3 1 in the corresponding label transferring head 18. Port 108 comu'iunicates with a transverse channel 108 shown in a wall of casing 109, (Figs. 11 and 12), and said casing has a channel 113 communicating with port 113 and with a port 11.3 opening within the casing. The valve 110 is provided with an angularlydis'posed channel 115 adapted to communicate simultaneously with port 113 and an air inlet relief port 116 in casing 109, when the valve is in one position, (Big. 11), and to communicate with port 108 and port 113 when the va ve is in another position. lVhen a label is to be attached to the label transferring head 18, with the latter bearing against the endmost label of a stack B, the valve 110 will be in the last named position and e haust induced through tube 11 1-, (through port 108), will cause exhaust in said head 18 to cause the label to adhere to the head. VJhen the head 18' has moved to the label delivering position the valve 110. will he rocked to the position shown in Fig. 11, so that exhaust through port 108 will be cut oil and at such time channel 115, by connnunieating with ports 118 and 116, will permit air to flow to the suction apparatus so that.

the label will be released from headflS against the adjacent end 'or side of a container A. Then head 18 is in. the last named position and the label has been released, with valve 110 in the position shown in Fig. 11, a channel 117, shown angularly disposed within valve 110 and spaced from channel 115, will communicate at one end with channel 108, (to supply heated air to port 108), and with a port 118 in casing 109, (Fig. 12), that communicates with a pipe 119 leading to a pressure apparatus or blower of anysuitable character, indicated at s in Fig. 1. The pipe 119 leads through an airheating device 120 of any suitable character, (Figs. 1 and l), shown comprising a casing containing an electric heating coil 121 of any suitable construction. hen the label applying head is in the label delivering position, as last stated, and valve 110 lVithinsaid casing 109 is a rotative The casingall ' was;

' the cam suddenly'sothat a blast of hotair will bel'blown against the label, and during the remainder of a ro'tatiouof said cam the arm 111 will be actuated to shift the osition of valve 110 in proper timing so tii started after the head'has engaged a label in the stack 13 and maintained until the.

label has been "presented against theend or side of a container, andsb on for each rotatlon of said'cam.

The parts of the machine so far described may be usedffor applying alabel'or la bels uponlthe' containers at one orboth ends or, sides ofthe same without reference to applying another label on such container. In; the example illustratedl provide means for, applying a label on the side of the container other than those previously speci'fie'd',' "j.'arrangedas follows'i Overa suitable stopping point of the conveyor, spaced froni'the labeling devices'previously described, is located a magazine 122 suitably supported from bracket .123 on table top 1 located in position over a label transferrer head'124,

The gripper 144 is pivotally connected at 148 with a link 149 that is pivotally connected at 150 with a sleeve 151 that ismounted to slide on an end of the extended part 124 of head 124 and on tube .126, (Fig. 8). A coil spring 152 within sleeve 151 bears at one end against the sleeve and at the other end against the part 124 tending to press the sleeve outwardly and, thereby through the link 149 to gripper 144 so that its tongue 147 will engage a label. At the label receiving position the outer end of sleeve 151 is adapted to engage a cam-like stop 153, and at the label delivering position said end of sleeve 151 is adapted to engage a cam-like stop 154, which stops are in position to push sleeve 151 and thereby through link 149 to cause gripper 144 to be moved out of the path'of the labels. The stops 153 and 154 are shown provided on a bar 155, which, between said stops, is bent laterally at 155 which bar is provided with longitudinal slot 156 in which thetube 126 slides, the

bar 155 being supported by an arm.157,

(Figs. 5 and 6). The part 155"- is at one side of the plane of stops 153, 154 and the bar is inclined laterally at 155 between the stops 153, 154 and the part 155, so that the sleeve 151, by means of spring 152, will be pushed along tube 126 when the head 124 is in position between the magazine 122 and the container A upon the. conveyor to cause gripping ofthe label on said head by the gripper 144 and tongue 147 while the label is:being transferred from the magazine to the container, so that when the label has been deposited upon the container the stop 154 will have pushed sleeve 151. to cause release of gripper 144 and tongue 147 from the label as indicated in dotted lines in Fig. 5. The

' slide 125 may be reciprocated in timed relation to the step-by-step travel of the conveyor, means for such purpose being arranged as follows A link 158 is pivotally connected with the slide 125 at 159 and its lower portion is pivotally connected with a rock arm 160 shown pivoted at161 on a support carried by table top 1", (Fig. 4), the arm 160 being pivotally connected with a depending link 1623. Said link is pivotally connected with a rock arm 164 journaled upon shaft 54 and shown provided with a projection 165 cooperative with a cam 16% secured on shaft 58, whereby for each rotation of said cam the slide 125 will be reciprocated so as to present the label receiw ing surface 1'24 of head 124 tothe lowermost label in the stack in magazine 122, whereupon exhaust induced through said head will cause a label to adhere thereto, and upon the descent of the slide the head will be lowered and rotate onehalf turn to present the label over a container then at rest hot air will be projected from head 124 through its ports 124 against the label, the ieat drying the same, in manner described with respect to labels B, the operation of valvellO controlling the exhaust through head 124 and the blowing of heated 'air through said head in timed relation to the same operations respecting labels B at head 18.

Before a label is applied upon container A adhesive is applied to the label as follows :Upon bar 10 is a rack 167 in mesh with a segmental gear 168 carried by upright shaft 169 journaled in bearings supported upon table top 1 (Figs. 1, 2 and 4), which shaft is provided with a corresponding arm 170 pivotally connected at 171 with a rock arm 172 that is pivotally connected with a link 173. The arm 172 is rotative on shaft 169. Link 17 3 is pivotally connected at 174 with a slidable frame 175 that is guided to reciprocate along ways 176 supported byframing 123. Upon the frame 175 is journaled an adhesive applying roller 177, (Fig. 2), adapted, when reciprocated by frame 175, to engage a supply roller 17 Sand to engagethe surface of a label upon the head 124 when the latter is temporarily at rest in the full line position shown in Fig.

. 5, before the label is placed upon a container below said head. The supply roller 178 is journaled in a tank 17 9 supported upon table top 1 by framing 123. The shaft of roller 177 is provided with a pinion 180 in mesh with a rack 181 carried by the guide7176, whereby roller 177 will be rotated as it is reciprocated. When said roller engages the adhesive supplying roll 178 the gear 180 will engage a gear 182 connected with the shaft of roller 178 and thereby rotate the latter to supply adhesive to roll 177. When paste has been applied to the upper surface of a label on head 124 the latter will descend and rotate to presentthe pasted label upon the container A beneath, as in the dotted line position in Fig. 5, the gripper 144 releasing the label. The roll 177 will retreat. When the head 124 next rises it will be rotated to present its surface 124 to the lowermost label C, and so on successively.

I provide means to sweep over a label placed upon a container A to cause its more perfect adherence thereto after having been placed thereon by the labclapplying head 124. 1.83 carried by a reciprocative head 184 shown provided with an angularly disposed stem or rod 185 extending upwardly and slidable in guides 186 carried by the frame 128, as upon arin 1.8.7 extended therefrom.

For such purpose I provide a brush (Fig. 4

mes i i The brush illustrated comprises aplurality of members. 183 provided with bristles at 183, said members being shown arranged in pairs and each pair pivotally connected 5 with the corresponding end portion of head 18% at 188, (Fig. 9). The adjacent ends of the members 183 01 each pair are inov-- ably connected together so that they may assume a substantially parallel position, as

1 indicated in Fig.1, or may assumea spread position, (shown in diamond-like'form), lllllSt 211611111 FIGS. 2 ands. For such ourpose the inner endof one member 183 is provided with a pin 189 operativein a slot 190 in the adjacent member. 7 On the upper side'of head 184 a member or disk 191 is rotative around the axis of stem 185 and links 192 are pivotally connected at 193 with member 191, eccentrically with respect to the axis of said member,.which links are pro.-

vided with pins or the like 194'tl1at extend through arcuate. slots 195 in head 18 1 and are connected to a member'183 of each pair of said members for actuating the latter,

her or disk 191' andis provided with an upwardly extending projection 191 adapted to engage spaced stops 196, 196 supported by frame 175, (Fig. 2). lVlien a labeled co1itainer comes to rest beneath. the brush the members 183 will be close together and the brush will descend to engage the label, as in Fig; 1. When the roll 177 moves from the paste applying position the stop 196 will engage arm 191 and rotate-the memberfor disk 194 in such a manner that the links 192 will cause the brush members 183? to spread, ,as indicated in Fig. 2," and when the frame 1 175 advances, (for causing'the rolllTT to 40' apply adhesive to a container beneath maga zine 122), thestop 196 will engage projection 191 and cause the member or disk 191 to rotate reversely, whereby thebrush members will be moved together in substantially parallel alignment, and so on each time for a container with a label C thereon. The head 184 is reciprocated above the containers in timed relation to the stopping of the same with the conveyor step-by-step. For

such purpose a-linl: is pivotally connected with a rock arm 198 that is pivotally supported at 199 on frame or bracket 123. A link 200 is pivotally andslidably connected with arm 198 by a pin and slot connection 201, 202, (Fig. l), said link depending through an opening in table top 1 and being pivot-ally connected at 203 with an Z111I1204h hung loosely upon shaft 54:, the free end o'twhich arm is provided with a projection or roller at 205 and reciprocativefbya cam;

206 secured on shaft 58, (Figs. 1 and 1)) Eachtime thatcam 206 rotates once 1311891111 198 185 An arm 191 extends from mem-- will be rocked to reciprocate the head up and'down in'such timed relat on to container A' beneath Said" head and to the i'eciprocations of the stops (Fig. 1), the head 18% will descend to'press the brushes upon the label on container A,
